I got a rb intake and a header I had on a 74 13b 4 port motor... blew it up... then bolted it on to my 76 13b motor... not enough power... now I bought a 91 rx7 with a series 5 turbo motor... blown up... thinking about rebuilding the turbo 2 engine... will the manifold fit? on my 76 I have a exaught leak on one of the rotor houseings... look like there is a hole that comes out sepret from the main exaughst port... will everything fit?

 

oh I forgot its a rb intake for a holley

 

no, they have different mounting patterns
